Netbooks with touchscreens?

Today I got to try an iPad for the first time. I was very impressed with the touch interface, especially the onscreen keyboard; but I was also disappointed by utter the lack of utility. (UNIX with no command line, ouch!)

Even so the experience was good enough that I'm considering purchasing something with a touch screen, and donating my current crop of laptops. Are there any netbooks, tablets, or whatever with touchscreens out there that can run a full Linux desktop stack?

Edit: FWIW something with stylus input and a physical keyboard would be acceptable, maybe even preferable. (As long as it wasn't too bulky - let's say no larger than a 10.5'' screen.)
